我们可以在highcharts中制作嵌套的圆环图吗？

Highcharts.chart('container', {
    chart: {
        type: 'pie'
    },
    title: {
        text: 'Nested Donut Chart'
    },
    series: [{
        name: 'Outer Ring',
        data: [{
            name: 'Category 1',
            y: 30
        }, {
            name: 'Category 2',
            y: 70
        }]
    }, {
        name: 'Inner Ring',
        data: [{
            name: 'Subcategory 1',
            y: 20
        }, {
            name: 'Subcategory 2',
            y: 30
        }, {
            name: 'Subcategory 3',
            y: 50
        }]
    }]
});
